3D GIS Requirements Document Now Available

The NENA Requirements for 3D Location Data for E9-1-1 and NG9-1-1 document establishes consensus requirements for operationalizing the use of 3D location data for 9-1-1. Specifically, this document provides concrete guidance for implementing recent FCC z-axis location requirements at the PSAP and communications center, and throughout the 9-1-1 ecosystem. The document assists the  9-1-1 community in operationalizing 3D location information delivered with 9-1-1 calls, as recently required by the FCC.

This document is divided into three parts:

• Informative material on the regulatory and technical background on 3D location in 9-1-1;
• Practical guidelines for implementing 3D location information in 9-1-1 systems today, including configuration and construction of 3D mapping information; and
• Calls for future standards work, including revisions to LoST, PIDF-LO, dispatchable location methods including civic address uncertainty, and handling of 3D shapes and structures in NG9-1-1—including initial work contributions to those efforts.
